In flight speak height is measured in 100s of feet and distance in nautical miles. For example a 747 will reach cruising altitude at FL370 (37000ft) but another plane may be FL360 (36000ft).
- p_l 7y ago"Flight speak" depends on multiple details that are not always obvious. For example, "feets" for altitude are "temporary allowance" and in many places are used only because of the influx of cheap US-made hardware. Flight Levels are actually not specified in meters nor feet, but in air pressure, so that if everyone has altimeters on the same "zero" pressure they will be able to communicate their flight level perfectly. Nautical Miles are used because unlike feet, they actually make sense.
